I’m looking for options to avoid using ISP (Tet) issued modem for my network setup, but not sure where to begin, I hope someone here can help with some advice.
ISP (Tet) is issuing modem/router/AP/switch combo device, but I’m not keen of using ISP provided hardware, instead I want to take ownership and full control of devices that I am deploying in my home.
Can someone please share insights, if its possible to install Mikroitk router with SFP port and optical transceiver to connect ISP optical cable directly in router and essentially avoid using modem? ISP modem have 4 LAN ports from which two are network ports (each have its own public IP address) and other two are used for IPTV.
Can someone please comment it this is possible to configure Mikrotik router so that modem can be fully avoided?
Yes, it might be possible, i have done this, but there is no general answer on how to achieve this if at all.
If you want a solution, you need to find out what the ISP uses to get the CPE connected.
I found a way to get configuration from Alcatel-Lucent I-240G-P. But only through uart.
Same steps may work for other Alcatel-Lucent devices.
Get root shell Alcatel-Lucent I-240G-P:
1.Connect uart(3.3v, but 5.0v also may be plugged) (5 pin connector on the middle of the board, (2,4) pins - IO, 3 pin - GND)
2.Plug in power to I-240G-P
3.Send Crl+A or hex ‘01’ when ‘Ctrl+A – Enter console terminal’ message appears, ‘[ONT Loader]’ should appear
4.Run command: ‘setenv bootargs ${bootargs} init=/bin/sh +m ; run bootcmd’, wait until '# ’ message appears
Next command should be executed fastly, otherwise device will reboot
5.Run command: ‘/etc/init.d/rcS’, wait until ‘INFO: ALL APPs are ready.’ message appears
Next command recomended to execute fastly, otherwise Console may cause problems (if ‘ONT>’ Console appears run commands: [‘enable’, ‘login’], enter User name: ‘CRAFTSPERSON’, enter Password: ‘ALC#FGU’, after that Console input ‘ONT>’ should disappear for a time)
6.Run command: ‘killall Console’
Done, next steps to enable login through ssh (which is more comfortable instead uart)
7.Run command: ‘killall dropbear’
8.Run command ‘dropbear &’
9.Connect ethernet cable to 1 ethernet port
10.Set ip address: 192.168.1.253, mask: 255.255.255.0, gateway: 192.168.1.251
11.Connect ssh to: 192.168.1.251 (password:admin)
Dump mib:
1.Login to ssh, or use ‘GponCLI’ command if connected through uart, ‘#ONT>’ should appear
2.Run command: ‘system’
3.Run command: ‘mib’
4.Run command: ‘dump’ ‘MIB is saved to the file /tmp/mibdump.txt’ should appear
5.Go back to system (Run command: ‘exit’)
6.Run command: ‘shell’
7.Run command: ‘cat /tmp/mibdump.txt’
Done
Using this I got ‘O5’ state with ONU id.
But no IP, (I still haven’t figured out the next steps (VLAN IDS, DHCP headers, e.t.c)).
I found a way to get configuration from Alcatel-Lucent I-240G-P. But only through uart.
I’ve tried using UART yesterday. I’ve managed to connect through Putty but only managed to connect to “user”. After “enable” couldn’t relog to a different user. Got some info from logs, but not much,.
If just wait until full boot there is 'ONT> ’ console with login.
The only ‘User name:’ I found is: ‘CRAFTSPERSON’ Password: ‘ALC#FGU’.
But after login through uart console closes and no any input will accepted until reboot.
This console also avilable through telnet(may not work until full reset) but after login there is only option to configure is SLID (PLOAM Password).
There is 3 different 'ONT> ’ console binary.
‘/bin/Console’ - login console (that appears after full boot)
‘/bin/GponSLID’ - very restricted, only SLID avilable, (appears after login ‘CRAFTSPERSON’ through telnet)
‘/bin/GponCLI’ - the full acces (avilable from 1 ethernet port after ssh server restart (dropbear))
Thoose binary also may be started after root shell got.
After command ‘/etc/init.d/rcS’ full booted I recomended to not wait too long because there is two consoles on same time and full access '# ’ console may be overlaped by 'ONT> ’ login.
If 'ONT> ’ login console appear you still can disable it for a time by login to it.
Recomend to kill ‘/bin/Console’ as soon as possible by ‘killall Console’ command, you can run it multiple times.
The boot log is not very informative.
I bought same device and compared logs, to find differences.
The uniqule values from log:
String starts with: 'Update timer:'
String starts with: 'Check base image file CRC:'
The strange part behind 'CPU revision is: 0001937c' and ' Linux version 2.6.21.7-cig-63'
My log looks like this:

Also there is some information in uboot console ‘[ONT Loader]’, but you should be very carefully with commands that writes information.
Were you able to log into the ‘[ONT Loader]’ uboot console? (Ctrl+A – Enter console terminal)
Some terminals may not handle Crl+A so you can try type Ctrl+A character (I not able to add it to this message but you can got it from ‘Hex to String Converter’ website, type ‘01’ and copy result) or if it has hex input you can send ‘01’
Edit:
Because some steps have to be done at a certain time and it is difficult to explain. I created a video on YouTube: Get root shell Alcatel-Lucent I-240G-P
Edit 2:
Also I dumped mib file from same device, but I do not know which operator used on that device before, so some values may be not actual to TET, but it still can be helpful: Alcatel-Lucent I-240G-P mib dump
This stuff harks back to the dark ages of FTTC or even ADSL. In those days, your router was direct on the incoming line and you needed to fiddle like crazy to get the best throughput. And the router the ISP gave you often dictated how you set up your internal network. So, yes, I can understand why people wanted to control their incoming lines.
These days, with FTTP, if the ISP gives you an ONT, just accept the ethernet interface it gives you. If it does not intervene in the operation of your own network, just leave it be. You can improve nothing by fiddling. Just put the ISP router in a cupboard, connect your Mikrotik router to the ONT and be thankful that there is a clear interface to the ISP. No more line stats, no more fiddling to optimise them.
ye, it would be nice if it was like that. except Im not getting even promised Minimum supported speeds and have I never even got above that number. Im paying for 1gig and getting 500mbit tops. You can say its not the routers problem and it might be, but better be safe than sorry. Then comes the whole bufferbloat issue, this router cant handle these speeds and low latency.
I didn’t delete any comments. I even can’t see it on moderation page. Now I disabled moderation again, (I disabled it on video upload but for some reason it didn’t turn off). Youtube moderation is weird.
Some values may be not valid or not where it should be because I still didn’t get IP.
